Abstract: The present invention relates to a camera having a beam splitter arrangement and a plurality of planar image sensor chips arranged in the partial beam paths thereof, which have nominal dynamic response for individual recordings of a finite range, wherein multiple image sensor chips spaced apart from one another with gaps are arranged in a first partial beam path and a gap-overlapping image sensor chip is arranged in a further partial beam path for at least one gap. It is provided in this case that the beam splitter arrangement is formed using a solid beam splitter block, the planar image sensor chips of the first partial beam path are adhesively bonded to a first surface of the solid beam splitter block, and the at least one gap-overlapping image sensor chip of the further partial beam path is adhesively bonded to another exit surface of the beam splitter block, and that the camera is furthermore provided with a sequence controller to record images with a dynamic response higher than the finite dynamic range.

Abstract: A method of producing a compressed video data stream (12) by compressing a stream of relatively high dynamic range video frames (2). A bilateral filter (3) extracts a base frame (4) with luminance information. The base frame (4) and the original frame (2) are used to provide a detail frame (5) with chroma information. A tone mapping operation (6) is selected (7, 11) and applied to the base frame to generate a relatively low dynamic range base frame (8), which is then compressed (9). The detail frame (5) is compressed separately. Final frame data (12) is then created, consisting of the compressed relatively low dynamic range base frame, the compressed detail frame, and stored information in respect of the tone mapping operation that had been applied to the base frame.

Abstract: The invention concerns a bidirectional reflectance distribution meter having a light source which illuminates a sample using pre-determinable elevation and a light receiver, which can be moved relative to the light source in order to receive light from the sample. To this end, it has been designed that the light receiver comprises several receiver elements to collect simultaneously a broad elevation angle range, and that at least one of the light receiver element and the light source is movable around an axis that extends generally vertical to the sample.

Abstract: The invention relates to a device for determining the distance of an object in local resolution mode, using a frequency-shifted feedback radiation source for irradiating the object with radiation that can be used to determine distance and using a position-sensitive object recording sensor. According to the invention, the frequency-shifted feedback laser for irradiating the object is equipped with an element for increasing the beat intensity of the emission frequency component and the position-sensitive object recording sensor is configured to record the beat intensity of the object and not the incoming radiation from the object.

Abstract: A fundamental concept of the invention consists thus in the fact that temporally variable reference and object light bundles are generated for object detection, the bundles are superimposed at a light receiver and detected beam by beam and the penetration of the object by selected beams is determined in response to the temporal variability of the superimposed beams.
